One app on China's radar is Zaker, which publishes information from newspapers, Web sites, and blogs. Another app is Chouti, whose motto is "Publish all that should not be published."

China already blocks many major foreign online news outlets and articles from its citizens. Mobile apps can provide a way around such blockades by including unapproved articles in their content. But the Chinese government has apparently gotten wise to such apps, vowing to shut down any that refuse to rectify themselves to follow local laws.
